- Milliken Mills Trails — This is a delightful network of trails on either side of Portland Avenue, with some interesting history. You can do a few shortish loops.
- Blueberry Plains — You can do a roughly one-mile loop here on the easy to follow but unmarked trails.
- Eastern Trail — A great bike path, with lovely off-road sections between South Portland and Kennebunk.
- Guild Park (aka Red and Blue Dot Trails) — Towering old trees in this old-growth forest make for a special, short walk.
- CLOSED: Ted Wells Memorial Trail — Short and easy, the trail brings you to a view of the marsh and connects via unmarked trails to the Manor Street trail system around the water treatment plant.
